Screw-locking insert

摘要

A screw-locking element in the form of an H cross-section profile is fitted into a longitudinal slot through a bushing sidewall that captures opposing recesses of the insert. When assembled to the bushing, the locking presents a base on the outside of the bushing and a screw-engaging longitudinal strip on the inside along the threads. The bushing may have more than one locking insert and the inserts are preferably composed on Nylon.
